Warm socks

Some people are more sensitive to the really low temperatures and keeping warm can be a real challenge. Most of the times, their feet are the ones to suffer the most. The warmest socks can go a long way in the harsh winters that many areas experience, and they’re most likely made of wool.

There are many people that buy the cheapest socks possible without ever wondering why some socks cost up to 3 times more. I must admit I was one of those folks. But are those pairs built better, warmer, do they last for longer? It is time we exposed the truth about them and find some socks that will make our feet happy.

Features to Consider before Purchase

So, you probably wonder what do people do to keep warm in the coldest weather. The answer is simple: some wear two pairs of socks to keep the cold at bay, while others wear the warmest socks ever. Sounds pretty easy, right?

Consider wool socks

Wool socks seem to be the answer to all the prayers related to having cold feet. There’s a reason for which wool is one of the best materials to make clothes from. The reason is that there is nothing like wool to keep warm in the cold weather or to maintain a cool temperature when it’s hot.

Wool Socks

Wool is one of nature’s best insulators, and there is no reason not to wear it when the temperature reaches below freezing point. Some socks made of wool are such good insulators, they can even be worn with sport shoes when you ride your bike on a really windy day.

You probably think that wool socks are thick, ugly, and itchy. This may have been the case when your great-grandmother was young, but these days things have changed. Wool can be treated to be thin, really soft and look stylish at the same time.

At the same time, wool socks these days are not always entirely made of wool. Instead the wool yarn is mixed in with other fibers that make it more durable.


People who stand or walk a lot a lot know just how important comfortable footwear is. At times wearing only shoes that are comfortable is not enough. Oftentimes, socks are something that get overlooked by many people.

However, these days it is possible to buy a pair of socks that will help increase the comfort level of your feet. In addition to keeping your feet cozy, a good pair of socks can help you while walking as well as you’ll feel less tired.

Comfortable warm socks

For a long period of time people thought that cotton socks are the best to wear at all times, however this is not really the case. Cotton socks get and stay wet if your feet sweat, something that doesn’t happen when wearing wool socks.

What’s more, is that wool socks can be hung overnight in some well ventilated place and have them smell as fresh as possible. This is not the case with cotton socks: these retain their bad smell even if you hang them in the same spot.

Foot specific socks

Making socks for each foot in particular helps with maintaining their shape for a longer time. If you don’t believe it, just inspect your regular socks and see how they got looser overtime, even if they’re still in pretty good overall shape.

There are two types of such foot specific indicators in socks: visual and tactile. The visual one is self-explanatory – all you have to do is to look at the pair and you’ll generally see a mirrored designed on them.

Foot specific socks

The tactile indicator requires the wearer to put the socks on the opposite feet and feel a difference, a slight discomfort. Some of the medium weight socks are also cushioned to offer more support and protection during a variety of outdoor adventures.

The cushions are placed on the sports that suffer more when walking, and are meant to protect and support the foot. These cushions are another indicator of which sock goes on which foot, as the discomfort will be hard to ignore when the socks are worn on the wrong feet.

What’s more, is that you can even find medium weight socks that are completely waterproof: you could be standing in a puddle  wearing just your socks, and having your toes feeling dry. Many of these socks are designed to dry fast even when you simply hang them.

The best socks to keep you warm in winter

Wouldn’t you like to see some socks that will really keep you warm in winter, and that fit the bill of the above descriptions? The wait is over as we compiled a short list below.

Wigwam The Ice Sock

Wigwam The Ice Sock

Height: Crew height

Specific features: Unisex, breathable

Best use: Hiking, outdoor, biking

Some people have to deal with cold feet all winter when going outside, no matter what they do or wear.

It’s perhaps time they tried these Wigwam The Ice Sock as they’re heavyweight thermal and meant to be worn with winter boots. On the downside your boots should be one size larger, or you won’t be able to wear them together.

Furthermore, the sizes are for men and the ladies should size the socks down if they want to purchase a pair for themselves. You’ll also notice that if you wear them while riding your bike, wind won’t even bother you.

As they’re made with wool among other fibers, you can wear these over and over without the need to wash them: they keep moisture away and as such your feet won’t smell. Many people are sensitive to real wool as it can itch, but the wool used in these socks is soft, and as such there will be no itching sensation.

Some people like to always wear their socks the same way as they did the first time. This is not always possible with most socks, however these Icebreaker Hike Plus Socks have a design to indicate how they must be worn.

Furthermore, if you were to ignore the visual markings, once they’re on the wrong way, they’ll feel uncomfortable, prompting you to switch them around. Cleaning them is easy as all you have to do is to wash them in the machine, according to the instructions.
